Problems solved by technology

However, due to the difference in the physique of the occupant or the difference in the seating posture, the chest protector moves to various positions and there is a possibility that the chest protector cannot be installed in an appropriate position with respect to the chest of the occupant.
In addition, in the event of a frontal collision, the chest protector cannot follow the front of the occupant, and may stop at the initial position and detach from the occupant's chest, and the chest protector cannot bear the load at the proper position

[0130] Next, use Figure 8 Describe the vehicle occupant restraining device 100 of the third embodiment. Further, the same structural portions as those of the first and second embodiments are labeled, and their description is omitted.

[0131] like Figure 8 As shown, a conduit 102 is provided in the vehicle occupant constraint device 100. A pad 104 is provided inside the conduit 102, along the cylindrical portion 46 of the insertion shoulder strap portion 22a. Although the illustration is omitted, the pad 104 is disposed in the occupant side of the seat. The liner 104 includes a hard pad 106 disposed at a position corresponding to the front side portion 42 of the conductor 102 and a position corresponding to the rear side portion 44 of the conductor 40 and is soft than the hard liner 106. Soft liner 108. In other words, the hard liner 106 on the front side of the pad 104 is formed of a material that is hard at the hard pad 108 of the rear side of the liner 104. For example, the har...

Abstract

The invention provides a vehicle occupant restraint device. The occupant restraint device for a vehicle has: a three-point seat belt device including a shoulder belt extending from an upper side in a seat width direction of a seat back of a vehicle seat to a lower part in the other end side in a seat width direction; a belt guide, Provided on the upper side of one end side of the seat back in the seat width direction, the shoulder belt is passed through, and arranged along the restraining surface of the occupant seated on the vehicle seat; the fixing part connects the belt guide The rear end portion of the belt guide is fixed to the shoulder on the seat width direction one end side of the upper part of the seat back; The clavicle of the occupant of the above-mentioned vehicle seat is closer to the front of the vehicle, and is harder to bend than the rear side portion in the longitudinal direction.

Description

Technical field [0001] The present disclosure relates to a vehicle occupant constraint device. Background technique [0002] Patent Document 1 (Japanese Laid-Open Patent Publication No. 2004-075015) discloses a chest member on a shoulder strap, and has a rigidity corresponding to a portion of the chest member and a passenger chest according to the rigid distribution of the occupant's chest. The structure of a changed liner material. In this configuration, the burden of the body is further reduced by substantially uniformly distribution of the body with respect to the body of the chest member during the chest constraints caused by the front collision. [0003] In addition, Patent Document 2 (Japanese Laid-Open Patent Publication No. 2015-123915) describes the following gas belt devices: expansion of airbags (e.g., gas belt) mounted in the shoulder strap (e.g., gas belt) in the shoulder strap (e.g.,). The pressure of the occupant is to withstand the pressure generated by the occupa...
